When a German U-boat sinks a freighter during WWII, the eight survivors seek refuge in a tiny lifeboat. Tension peaks after the drifting passengers take in a stranded Nazi. Hitchcock saw a great challenge in having the entire story take place in a lifeboat and pulled it off with his usual flourish. In 1989, the film "Dead Calm" replicated the technique. From a story by John Steinbeck. Bankhead shines.
